FANLIGHT-OPERATING MEANS.

Q Application filed July 21,

To all whom it may concern.

Be it known that we, EDWARD FRANCIS VVILLOU'GHBY and EDWARD MALET BARFORD REVILL, subjects of the King of Great Britain, residing at 10 Stirling street, Ber-hampore, and 207 Onepu road, Lya-ll Bay, Wellington, New Zealand, have invented a new and useful Improved Fanlight-Operating Means; and we do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to improved means for the opening and closing of fanlights, and other like windows or ventilators, of the class in which a vertically sliding rod mounted in bearings alongside the fanlight is connected to the fanlight by levers so designed that the sliding movements of the rod will open or close the fanlight.

The present invention has been devised in order to provide a simple construction of such an appliance, embodying means for the tight closing and locking of the fanlight in the closed position.

According hereto, the operating rod is mounted in its bearings to move alongside one side of the fanlight frame and to extend downward at its lower end so that it may be reached and worked from the floor. The upper end of this rod is pivotally attached to the upper end of a lever whose lower end is articulated to the fanlight frame and so disposed that a downward pull on the rod will open the fanlight, while an upward ush thereon will close the fanlight by turnm the lever in.

The invention consists in an improvement in the construction of the said lever by means of which the fanlight will be jammed tight, and locked on the closing movement of the operating rod and will be unlocked, and started, on the opening movement of such rod.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the operating means in position to actuate a fanlight and showing the fanlight closed.

Fig. 2 is a side elevation thereof, showing the fanlight opened in dotted lines.

Fig. 3 is a side elevation and Fig. 4 a plan of the locking means.

A is the operating rod that is mounted in fixed guides B arranged adjacent to the line Specification of Letters Patent.

of the fanlight C, so that it may move up and down therein. D is the set screw for locklng the rod from movement. E the lever that is pivoted at one of its ends to the top of the rod A and at theothcr is pivoted to a bearing K fixed on the fanlight (l so that the up and down movements of the rod, will move the fanlight out and in on its hinges in the manner that is alreadv well known. I

In this invention the lever E is formed as a compound lever by being made with a olnt 6 near its lower end and this joint provldes that in the operation of the device, the downward pull on the rod A to open the fanlight will first turn the shorter end E of the lever down and outward on its pivot before the main length. ll turns outward. to open the fanlight. Likewise on the closing operation the upward push on the rod A to straighten the lever and turn its top end E in, will at the end of the movement, give the shorter lever end E an upward movement on its pivot. This movement of such lower portion E is designed to cause it to lock with a locking device fixed to the fanlight frame G, and the downward movement to free it from such device, so that the locking and unlocking of the sash will automatically take place upon the respective operations of the rod. Such locking device is formed by a bracket F fixed to the frame G and having a slot F in it, extending from its lower end, within which a pin H on the joint 6 of the lever will fit and jam. This jamming action, in addition to locking the device, will also give a final tightness to the closing of the f anlight, while the first portion of the opening movement by which the lever end is freed from the lock, will start the fanlight andlthereby facilitate the opening of a tight sas In order that the shorter lever end E may be prevented from turning on its pivot during the ordinary movements of the rod A to open and close the sash, and thus insure that the locking pin H will remain in the position to be forced upward into the catch 4 on the closing of the sash, the joint by which such lever is attached to the bracket K is made of a frictional type by the interposition of a spring washer is (Fig. 4) between the lever end and the hearing. The compound lever in its ordinary opening and closing movements, will therefore turn on its joint 6, as clearly indicated by the dotted lines in Fig. 2.

Vi e claim 1. Fanlight operating means comprising a rod mounted for longitudinal movement, a bracket for attachment to a fanlight sash a bracket for attachment to the frame and having an open-ended slot, a link pivotally connected to the firstnamed bracket, a second link pivotally connected to the rod, and. a pivot connecting the said links together and arranged to enter the said slot.

2. Fanlight operating means comprising a rod mounted for longitudinal movement, a bracket for attachment to a ianlight sash, a

bracket for attachment to the frame and l1:1\- ing an open-ended slot, a link pivotally connected to the first-named bracket, friction tensioning means for said pivotal connec tion a second link pivotally connected to the rod, and a pivot connecting the said links together and arranged to enter the sa id slot.

In testimony whereof, we have signed this specification in the presence of two subscribing witnesses.
